ALFRED JOHN norm, or nmmmennmnnomnn oononnzrn AND LIKE s'rmrc'runn Specification of Letters Patent- Patented Apr. 26, 1921.

Application filed December 23, 1918. Serial No. 267,974.

Be it known that I, ALFRED J OHN DUNN," F. R. I. B. A., subject of the Kill of Great Britain, residing at Clarendon h mbers, Waterloo street, Birmingham,- England, have invented certain new and useful Improvements in and Relatin to Concrete and like Structures, of which the following is a specification.

This invention comprises improvements in and relating to concrete and like structures and has for its object to improve the construction and facilitate the erection of concrete and like buildings or structures.

While tlfe more'usual method of reinforced concrete construction at present in use consists of casting the main members,

' such as pillars, piers, etc., i/nsitu, between pieces, piers, intermediate standards or like vert1cal members, to secure more effective keying of cast concrete or cement walls and the like thereto to enable the walling to be finished flush with the members when desired avoiding unsightly projections of the members, and to facilitate fixing in position the door and window frames.

The pillars, corner pieces standards, and the'like are formed witha central body portion, which may be solid and reinforced in any suitable manner, if desired, of substantial cross section, from which keying nibs or iillets project. The projecting keying'nibs or fillets are formed with angular terminal edges, each edgebeing preferably in the central vertical plane of the projection, and the preferred inclination for the sides of the angular edge is such that the-angle between them is a right angle. It is preferred that the oppositely inclined edges of' the angular edge directly meet the respective plane sides of the body of the standard pillar or the like so that no intermediateshoulder is formed between the plane sides of the member and the inclined sides of the keying edge, so that flush finishing of the walls and members may be effected. It will be understood that the relative inclination of the sides of the angular edge may vary from the right angle above specified, but

that is believed to be the most effective compromlse between the better keying effect of a more pronounced angular projection with the cast concrete and the lateral strength of th projection and its liability to fracture from shock or otherwise.

It will be understood that one, two, or more of these keying nibs or fillets will be formed on each face of a member to which a wall, partition or the like is to be formed by casting operation or by slab work erectlon in the known manner. Where two projections from the face of a member occur it is preferred to have the intervening space equal to the width of the base of the angular fillet or nib, but this is not essential and the space may be larger or less as desired.

In conjunction with such'filleted members i the sole members or beams or brestsummers .may have a central projecting cog or rib on one or more faces which cog or rib in width corresponds with the intervening space between the projecting keying fillets from the pillars, standards, or the like.

The pillars, standards, or the like at their" uppei and lower ends have projections leavmg an intervening space and thus the p11- lars, etc.,,may be interlocked on a cogged S sole or sill at the base and may have a cogged or ribbed beam, bres-tsummer or the like similarlyinterlocked with their upper ends, on to which beam or the like further standards may be locked, and so on, which greatly facilitates the erection, of a prepared concrete or like skeleton to receive the concrete walls and the like, which are cast in site onto thekeying nibs or fillets of main members.

Similarly window or door j ambs, whether of wood or of concrete, may have projections to enter the intervening spaces, between the projecting fillets, of pillars,

the

standards, and the like, and flared away sides to seat against the angular faces of the said keying fillets or nibs to facilitate their fixing. Similarly the window or door heads or lintels and sills may be cogged 0r grooved and locked in position whether on the top or the underside, according to the class and position ,of the member.

The central cogging or ribbing of beams,

brestsummers and the like in addition to permitting joggle jointing of the same with the pillars, standards, and the like, forms supporting ledges or abutments for receiving the cast concrete or slab work walls,- floors, or the like. I do not claim per se the idea of a keying projection and recess between piers and the like and sills, sole members or beams as this has been proposed before.

On the-drawings: Figure 1 is an isometric view showing. y improved construction of piers or like main members and beams, and shuttering for casting in the walling.

Fig. 2 is avertical sectional view of a wall of a two story building.

Fig. 3 is a sectional plan showing various forms of vertical members in use, and shuttering for the walls is shown in position.

Figs. 4:, 5, 6, 7, and 8 are sectional views of vertical members for single wall construction.

Figs. 9, 10, 11, 12, and 13, are isometric views showing the connections of such members to sole plates and the connection of beams and the like to the members.

Figs. 14, 15, 16, 17, and 18, (Sheet 2) are sectional views of verticalmembers for double or cavity wall construction.

Figs. 19 to 23, show the construction of the bottoms and upper ends of the members shown at Figs. 14 to 18 for theirconnection to sole plates and for the connection of beams and the like to them.

Fig. 24 (Sheet 3) shows in horizontal sec- 1 tion the mounting of a door on a single wall member.

Figs. 25 and 26 are similar views to Fig. 24:. showing respectively an inside and an outside door mounted to members of double or cavity walls.

Figs. 27 and 28 (Sheet 4) are isometric views showing respectively a window head and sill mounted to double or cavity wall members.

Fig. 29 (Sheet 1) is a detail of a securing device for the supporting members of shut tering boards.

Fig. 30 is a detail of a special form of wall tie which supports internal shuttering boards. 4

Fig. 31 shows counter wedges for securing internal shuttering boards.

As shown in Figs. 1, 2, and 3, the main vertical members, stanchions, piers, or the like, are formed with a solid and suitably reinforced body a and one or more keying and locking fillets or nibs b projecting from the body. Each nib or fillet has an angular terminal edge, as set out above in the general statement of the invention and which is clearly shown at b. It. will be understood that the cross section of the vertical members will depend on the particular purpose of use. At Fig. 1 the vertical piers shown are for use with double or cavity walling and consequently from each face to which a at d between two lengths of walling, a fur.

ther pier at e to which a single thickness party wall is joined, and a smaller intermediate member in a main wall at From this typical example and the various cross sections of vertical members for use in single walls, shown at Figs. 4 to 8, and for cavity walls as shown at Figs. 1 to 18 the nature of the construction to be provided to meet ordinary cases will be clearly understood. I

The cast concrete walling iskeyed effectively to the piers or other vertical members by being cast upon the fillets b, and in a similar way slab work may be keyed to the vertical members if the end slabs are formed with recesses corresponding to the angular fillets b.

To lock the vertical members upon sole pieces 01' the like each vertical foot of the member is formed with a groove g, see Fig. 1, Figs. 9 to 13, and Figs. 19 to 23, which groove g sets over a cog h of the sole piece or like horizontal member.

Similarly the upper ends of the vertical members are provided with grooves j to receive cogs 71: formed upon the horizontal members, such as beams and the like which are supported on the vertical members. Figs. 9 to 13 and 19 to 23 show particular examples of the forms of the grooves j in the vertical members to suit various conditions of use as there illustrated.

By means of this jointing between the vertical members and the horizontals the erections of the main skeleton of a building is greatly facilitated as the individual members are much more readily retained in position while the casting in of the walling or the erection of slab walling takes place. Further the continuous cogs upon the horizontal members form supporting edges between the vertical members to receive the cast or slab walling, and where double walling is used, insure the locking of the walls to the horizontal members as well as to the I vertical members.

of the fillets b of the member a. For an outside door a stout door frame 1" fitting between the fillets. b and shaped to seat against boardsto t e main members for casting the angular faces of Same is all that is required. The door head will in each case be notched or grooved in its ends to seat upon the fillets b of the member a.

Similarly with window frame mountings, an example of which is shown in Figs. 27

and 28, the jamb s isshaped to fit within and against the two fillets b and the ends of a the head t Fig. 27 and sill u Fig. 28 are grooved or notched at the-ends to seat on the angular fillets b. For cavity walling it is preferred to cog these parts, with the continuous cogs is as with the other horizontal members before described. The figures show concrete cement -or like frames but wood frames may be similarly arranged.

For the urpose of supporting shuttering concrete, cement, or like walls or partitions thereto, I ma ,provide angle irons; as at n Figs. 1, 2, an 3 supported at the bottom by a clamping bolt '10, passing through the sill or sole member from one side tothe other. At the top the angles are supported by yoke pieces :12 andcross bolts 3 and by means of the construction of the yoke a: shown at Figs. 1 and 29 which 'clampsover the beams or other horizontal members andhas a series of holes a in the vertical limbs,vertical ad.-

justment may be readily efiected. Lateral adjustment may alsd be provided as shown at 1 Fig. 29. so that the vertical limbs may be spaced out from the angles by distance piece 2 slipped over the bolts 3 to accommo ate. moldings or'the like formed on the horizontal members. At Figs. 1, 2, and 3,

the shuttering boards are shown in place for the casting in of the double or cavity walls 3, the outer shutterin boards 4 being secured against the vertlcal members by the choring angles 1: and the inner boards 5 may be dropped into special wall ties 6 Fig. 30, which have central taper projections to insure correct placing of the boards and the superposed boards which are inserted, as the work proceeds may be secured by counter wedges or co-actin'g inclines as-at 7 Fig, 31.

One of the counter wedges is provided with side flanges and with an overhanging an- Instead of the square'cogs is upon the horizontal members I may employ angular projections similar to the fillets b of the .vertical members, or projections with plane end surfaces'and taper sides, the grooves of the heads and feet of the uprights being correspondingly shaped to receive the projections. The vertical members "-'i nstead of bemgformed ascomplete units 'may comprised of a number of cast blocks 'sultabl connected together but provided with t e angular fillets so as to conform tothe unitaryange 8 to. maintain its position.

structures illustrated. The tops and bottoms of these blocks will be grooved and cogged similar to the top of the vertical members and under sides of the beams already described. If lateral keyin .means be desired keys can be inserted in ateral slots cut in the members.

I claim 1. In a structureof the class described,

a vertical member having a vertical fillet or' fillets on one side, each fillet being provided with oppositely beveled faces which converge to form an edge, said faces being at right angles to each other, and a molded wall member one end of which is joined to said vertical member and keyed by said fillet.

2. In a structlire of the class described, avertical member. having a vertical fillet or fillets on one side, each fillet having oppositely beveled faces which converge to form an edge, said faces being at right angles to each other, the fillets terminating flush with the plane surfaces of the member to enable the walling to be finished flush .with the member, and a molded wall member one end of which is joined to saidvertlcal member and keyed by said fillet.

a vertical member having a vertical fillet.

a vertical.v member having spaced vertical fillets on one side each of which is provided with oppositely beveled -faces which converge to form an edge, said faces being at right angles to each other, saidniember' also having recesses in the ends-extending thereacross and arranged between said fillets; upper and lower horizontal members extending across the ends of the vertical memher. and having longitudinal flange projectionson' theiropposing sides,.end portions of which are engaged in said recesses of the vertical member, andspaced and moldedwall members between said vertical and horizontal members, spaced apart by. the intermediate ortion of the flange projections of the orizontal members and having ends joined. to said vertical member and .keyed by the said fillets theredfi In testimony whereof I aflix my signature.
